Does partial reflection and refraction occur when light travels from a slow to fast medium? Explain.

Hi Davina :) Yes, partial reflection and refraction will occour because the incident ray will refract if it has not reached the critical angle. Once the ray reaches the critical angle of the first media they ray will start to totally internally refract, in summary. Yes it will unless the angle is past the critical angle

Light partially reflects and refracts when it moves from a slow medium to a fast medium, as long as the angle of incidence is less than the critical angle. If this angle exceeds the critical angle, total internal reflection occurs. This behavior is due to the differences in the speed of light in the two media.
